A custom development board built around the Raspberry Pi RP2040 microcontroller.
This project is a personal PCB design exercise based on the official RP2040 hardware-design reference material. The goal was to translate the reference design into a complete, organized KiCad project and develop a practical DevKit-style board around the RP2040.
Project status: PCB design / hardware development
The board was designed from the RP2040 reference design with attention to the complete hardware implementation rather than treating the microcontroller as a standalone component. The repository contains the KiCad schematic and PCB layout, supporting component data, manufacturing-related outputs, and visualizations of the finished board.
The design includes the supporting circuitry required around the RP2040, including its clocking and other core hardware, while keeping the board in a compact development-kit form suitable for experimentation and further firmware development.
The main hardware design is provided as a KiCad project:

The first layer of the PCB, showing the routing and copper features placed on the top side of the board.
The second PCB layer, showing the corresponding internal copper features and routing.
The third layer of the four-layer PCB stack, providing additional routing and copper area within the board.
The final layer of the PCB stack, showing the copper features on the bottom side of the board.
All four PCB layers displayed together to give an overall view of the board's routing density and layer organization.
The following renders show the completed PCB from different perspectives. They provide a more intuitive view of the board outline, component placement, connectors, and overall physical arrangement.
A perspective view of the assembled PCB, highlighting the component placement and overall board geometry.
A second perspective of the board showing the physical arrangement from a different angle.
A final 3D overview of the DevKit, showing the complete board design as a physical assembly.
The board was developed by studying the RP2040 hardware reference design and adapting its requirements into a custom PCB workflow:
The design was developed with the RP2040 hardware design documentation as a primary reference. The relevant reference material is included in the ref/ directory for reproducibility and study.
This repository represents a custom hardware implementation and learning project. It is based on the RP2040 reference design, but the PCB, schematic organization, component selection, and physical layout were developed as part of this project.
The design should be reviewed and electrically validated before being used as a production board.
